 Norwood Russell Hanson

Norwood Russell Hanson (1924–2017) was an influential American philosopher and physicist, best known for his work in the philosophy of science, particularly concerning the nature of scientific observation and the interplay between theory and observation. He is perhaps most famous for his concept of the "theory-laden" nature of observation, which suggests that what we see and how we interpret data are significantly influenced by our existing beliefs, theories, and frameworks.
